HAY ELEVATOR AND CARRIER.

SPECIFICATION forming part of Letters Patent No. 318,085, dated May 19,1885.

Application filed October 4, 1884.

To ctZZ whom it may concern.-

Be it known that I, MARoUs -W. CHAMBER- LAIN,2L citizen of the UnitedStates, and a resident of Branchville, in the county of Sussex and Stateof New Jersey, have invented certain new and useful Improvements in HayElevators and Carriers, of which the following around and upon which theoperating-rope is made to work, and which are made with fixed journalssecured thereto or integral therewith, in slotted journal-bearings soformed in the frame that while the loaded pulley is held in positionwhile performing its office it may be readily removed from its bearingsin the frame. The pulley-wheels are made interchangeable the one withthe other in their respective bear- 2 5 ings.

My invention furthermore consists in pivoting the bolt-plate upon aloose pin resting in vertical grooves or slots in the frame, and inmaking the opening through the plat. e larger 3 than the pivotal pin, soas to allow a slight play or rocking of the plate upon the lockinglugsbefore the plate begins to revolve upon its pivot.

In the accompanying drawings, Figure l is 3 5 a side elevation of ahay-carrier mounted upon a track, the frame being broken away in placesto illustrate my invention; and Fig. 2 is a partly-sectionalview of theslotted j on rnal-bearing.

A is the carrier-fram e, mounted upon a trackrail, B, and is providedwith wheels or rollers resting on said rail.

0 D are the pulley-wheels over and around which the operatingrope K ispassed. This rope K is in all ordinary cases secured by one 5 end to oneof the pulleys, as at O, andispassed from there down around a pulley, E,mounted in a bail, I, to which the load is attached, and which serves,as hereinafter described,to secure the load in its elevated position.The pulleys G and D are fixed. upon their shafts or (No model.)

journals, and upon the inner faces of the frame are formed sockets or journal-bearings F, open toward the top, so that when it is so desiredthe pulleys may be removed from their bearings, and the pulleys being ofthe same form and size, they may be changed about from end to end of theframe. The bolt-plate G is mounted in the central part of the frame insuchposition that the locking hooks or bolts formed upon its lower sideswill be in position to pass through the bail I when it is passed intothe frame A. This plate is mounted upon a pin, H, which is itselfmounted in vertical slots or grooves upon the inner faces of the frameA, so that it mayhave a limited vertical movement, but no movement fromside to side. The opening in the plate G through which the bolt or pin Hpasses is enlarged laterally, so as to allow a limited side movement ofthe plate before it begins to rotate on its bearings,and this is foundto greatly assist in moving the plate when it rests upon the lockinglugs h 71, upon which the plate rests when the load is suspendedtherefrom. The stop-block L is secured to the track B in position to en-5 gage the vertical slot in the upper side of the plate G, and when thebolts upon the under side of G are in position to allow the entrance ofthe bail I, and resting with their ends against the locking-lugs M, theblock L serves to hold the frame A in position. S0 soon,however, as thebail I enters the frame and presses up on the plate, the carriage isfree to more, and such movement will cause the plate G to rotate andpass one of its bolts through the bail I, and thus secure theload to thecarriage.

When it is desired to free the bail I, with its load, from the carriage,the lateral move ment of the plate G upon its pivotal pin, by reason ofthe laterally enlarged opening through said plate, will greatly decreasethe frictional contact of said plate with the lugs 71, and allow a readywithdrawal of the boltplate from said bail.

Having described my invention, what I claim is- 1. In a hay elevator andcarrier, the combination, with the carriage and the pulleys mountedtherein, of the slotted journal-bearings F, formed within the frame, andadapted ICO 10 ing through a laterally-enlarged opening in the plate,substantially as and for the purpose set forth.
